To offset this, however, one must remember that there were popular fetes and sacrifices of a more general nature, to which many were invited and in which even the lower castes took part; and these were also of remote antiquity.
Already current in the Br[=a]hmanas is the phrase 'man's debts.' Either three or four of such moral obligations were recognized, debts to the gods, to the seers, to the Manes, and to men.

Whoever pays these debts, it is said, has discharged all his duties, and by him all is obtained, all is won.

To the gods he owes sacrifices; to the seers, study of the Vedas; to the Manes, offspring; to man, hospitality (_Cat.Br_.i.7.2.
